Thunderbird Conversations is a Thunderbird extension which, as the name implies, enables a conversation view in your Thunderbird. Notable features include:- a regular conversation view that fetches messages from all folders, and behaves just like Gmail’s- a quick reply feature, with autocomplete, that allows you to reply to a thread in a snap,- quoted parts are collapsed,- keyboard shortcuts,- and a few other bonus features.

Version Information

Version 2.8.1
Released August 5, 2014
1.1 MB
Works with
Thunderbird 29.0a1 and later

This release brings several new improvements.

New features.- The address for replying can now be changed in the quick reply.- The "quick reply" feature now uses an HTML editor (#369), meaning that no loss of formatting occurs when replying. The message will be sent as HTML only if necessary (just like the regular composition process). This fixes several other issues related to signatures (#353, #644, #779). The hidden, unsupported compose-in-a-tab feature provided by this addon hence also uses HTML composition.- New "open" action for attachments added to a quick-reply.- The "open messages in: a new window" preference (in Advanced > Reading and Display) is now honored. This means that you can open a conversation in a separate window by flipping this preference and double-clicking on a message in the thread pane, or hitting the "pop out" button in the conversation toolbar.- Support for the DKIM verifier addon.- Option to always collapse signatures.

Bugfixes.- Fix the Lightning plugin support.- Contact tooltips now display properly even when the message is collapsed.- The addon no longer waits for images to load before reflowing and adjusting the height of a message.- Several other bugfixes related to changes in Thunderbird.

Help wanted!- I don't expect to have much time in the upcoming few months. If you wish to see a feature implemented, please feel free to have a look at the code and send pull requests!
